Hydraulic Accessory Cast Steel Check Valve Hydraulic Lock for Mini Excavator
A hydraulic lock, also known as a Pilot Operated Check Valve or Pilot Operated Locking Valve, is a type of valve used in a hydraulic system to control the unidirectional flow of fluid and to be able to lock the position of the fluid when needed.
The principle of operation of a hydraulic lock usually involves a main valve and one or more control valves.The main valve controls the unidirectional flow of fluid, while the control valves provide opening or closing control of the main valve by controlling the supply of pressurized oil.
Hydraulic locks can be designed in different forms including, but not limited to, slide-valve type, ball-valve type, etc. to accommodate different operating pressures, flow rates and installation requirements.

How Does It Work?
Hydraulic locks typically operate via check valves or pilot-operated valves. A standard check valve restricts fluid flow to a single direction, maintaining pressure within a specified section of the hydraulic system. Conversely, a pilot-operated check valve, integrated with an additional control feature, can unlock under certain conditions, such as the application of pilot pressure, thereby effectively releasing the lock.
